Another brick in the wall

My husband just arriving home (he helped a colleague moving to his new home):

My husband: ‘.. and so he was living very close, just opposite us, but he lived on the 1st floor looking on a brick wall.’

Me: ‘Oh good, so he couldn’t see me sunbathing naked in the garden.’

He: ‘No, he couldn’t.

That’s why he always needed to visit his upper neighbour on the 3rd floor.

… but relax, this neighbour only let him on the balcony if my colleague paid enough..

.. provided, of course, that there was still room on the balcony due to all other neighbours.

.. Unfortunately due to this disadvantageous feature he could sell his apartment on the 1st floor well below price and…’

Me: ‘Guess this would be enough info, thanks.’
